Agentic State Engine — event-sourced causal graph with branching, decision traces, and realtime sync for AI-native applications

/**
 * Timeline Svelte — `createTimelineStore` store-contract bindings
 * (ADR 0034 wedge 3).
 *
 * Import from `trellis/timeline/svelte`:
 *
 *   const timeline = createTimelineStore({ duration: 90 });
 *   // In markup: <div style:width={`${$timeline.progress * 100}%`} />
 *
 * No dependency on the svelte package — only the store contract, so it
 * works across Svelte 4/5 (see `src/svelte/stores.ts`).
 *
 * @module trellis/timeline/svelte
